【発明の開示】
【課題を解決するための手段】

【化1】
【0003】
驚くべきことに、R=
− 水素、
− ヒドロキシル、
− C原子数が10以下のアルコキシ基、
− C原子数が10以下の直鎖もしくは分枝鎖の、飽和もしくは不飽和アルキル、
− C原子数が10以下のアルキルチオエーテル基[このチオエーテル基はチオエーテルブリッジ(bridge)を介して芳香環に結合している]、

− 酸素および/または硫黄原子が1個以上割り込んでいるC原子数が10以下のアルキル、
である前記式1で表される化合物が抗菌活性を示すことを見いだした。
【0004】
前記化合物の各々、並びにこれらの混合物は
(a)ふけの原因となる微生物を化粧的に処置する目的、
(b)体臭の原因となる微生物を化粧的に処置する目的、
(c)アクネ(acne)の原因となる微生物を化粧的に処置する目的、
(d)真菌症の原因となる微生物を化粧的に処置する目的、
(e)無生物材料の上または中に存在する微生物を処置する目的、
および/または
(f)腐敗し易い製品を保存する目的、
の抗菌活性化合物または活性化合物混合物として用いるに適する。
【0005】
人の皮膚にはいろいろな細菌が多数住み着いている。このような細菌の大部分は病原性ではなく、皮膚の生理学的状態および皮膚の臭いに関係していない。他方、他の細菌は皮膚の健康状態に決定的な影響を与え得る。人の皮膚のフローラ(flora)に実質的な影響を与える微生物のいくつかを表1に挙げる。
【0006】
【表1】
【0007】
体の中で生産される物質および汗の中に含まれる物質、例えば不飽和脂肪酸などが細菌によって分解を起こし、その結果として、多少とも弱い臭気を有する前駆体から身体の良い状態にひどく影響を与える可能性がある不快な臭いを有する分解生成物が生じる。化粧品では、体臭の一因になる物質の生成を防止する目的で、体の汗の発生を抑制する製品(いわゆる制汗薬)または人の皮膚の細菌(臭いの発生の一因になる)の増殖を抑制する物質(脱臭薬)が用いられる。腋の下および足の臭いまたは体臭の発生では一般に表皮ブドウ球菌、コリネバクテリウム・キセロシスおよびブレビバクテリウム・エピデルミジスなどの如き細菌種が決定的な一因になっている。従って、化粧品産業では、前記および他の体臭(腋の下および足の臭いを包含)の原因になる微生物を処置するための新規な作用剤が継続して求められている。
【0008】
アクネの原因になる微生物はざ瘡プロピオンバクテリウムであり、これは嫌気的に増殖する微生物である。化粧品産業は、そのような微生物およびアクネの原因になる他の微生物を処置するための作用剤を絶えず探している。
【0009】
人の皮膚の領域は全部が真菌による感染[特に皮膚真菌症(dermotomycoses)および爪真菌症]を受け得る。衣服、靴または宝石を着用する結果として水分および温かさが蓄積される可能性のある皮膚領域が特に頻繁に影響を受ける。指爪および足爪領域の菌・カビによる病気が特に不快さを感じる病気である。白癬菌属および表皮糸状菌属のいろいろな種がしばしば真菌症発生の決定的な一因になっている。化粧品産業は、前記および他の真菌症の原因となる微生物を処置するための新規な作用剤を絶えず研究している。
【0010】
加うるに、髪手入れの分野では、微生物であるマラセジア・フルフル(これはふけ発生の決定的な一因である)およびふけの原因となる他の微生物を処置するための物質を強力に研究している。
【0011】
本文脈の範囲内で、「処置」は、関係する微生物の繁殖を抑制しそして/または関係する微生物を死滅させる手段を用いて前記微生物に何らかの形態の影響を与えることであると理解する。
【0012】
その上、化粧品および薬剤産業では、腐敗し易い化粧品もしくは薬剤製品の防腐で用いるに適した作用剤が絶えず求められている。
【0013】
相当する抗菌活性剤および/または防腐剤を研究する時、化粧品および/または薬剤製品で用いられる物質は
− 毒物学的に受け入れられ、
− 皮膚が良好に受け入れ、
− 安定であり(特に通常の化粧品および/または薬調剤の中で)、
− 好適には無臭であり、そして
− 製造が安価である(即ち標準的な方法を用いそして/または標準的な前駆体から出発)
必要があることを考慮に入れなければならない。
【0014】
前記特徴の1つ以上を充分な度合で有する適切な(活性)物質の研究は本分野の技術者にとってより困難なことである、と言うのは、一方ではある物質の化学構造と他方ではそれが特定の微生物に対して示す生物学的活性および安定性の間に明瞭な依存性が存在しないからである。その上、抗菌作用、毒物学的受け入れ性、皮膚による許容性および/または安定性の間に予測可能な関係も存在しない。
【0015】
従って、本発明の目的は、この上で考察した微生物の中の少なくとも1種に対して活性を示す、好適には数種の微生物に対して活性を示しかつ好適にはまたこの上に挙げた付随的条件の1つ以上も満足させる抗菌活性化合物を示すことにあった。
【0016】
驚くべきことに、最初に挙げた4−メチル−4−アリール−2−ペンタノール類(R基が示した意味を有する)が卓越した抗菌特性を有しかつ全系列の微生物に対して活性を示すことをここに見いだした。
【0017】
前記式1で表される化合物の中で、4−メチル−4−フェニル−2−ペンタノール(CA番号2035−93−0、2R/S混合物;329313−22−6、2R異性体および329313−20−4、2S異性体)および4−メチル−4−p−クメニル−2−ペンタノール(CA番号:93963−35−0;R=i−プロピル)化合物は公知である。しかしながら、前記物質が抗菌活性を有することは今まで報告されていなかった。加うるに、4−メチル−4−フェニル−2−ペンタノールが特定のグリコリシス抑制作用を有することはJ.Dental Res.40,384(1961)から公知ではあるが、その理由は、前記物質が抗う食性活性物質として適切であることによる。しかしながら、前記物質が抗菌活性を有することは今まで報告されていなかった。
【0018】
前記式1で表されるアルコールは、人の皮膚に存在していて臭気を発生する微生物に対して強力な抗菌作用を示し、従って、化粧品などで公知の抗菌活性化合物[例えばファルネソール(farnesol)など]の優れた代替品または補足品として脱臭薬として使用可能である。本発明に従う式1で表される化合物は、また、ざ瘡プロピオンバクテリウム、マラセジア・フルフル、および真菌症の原因になる微生物、例えば毛瘡白癬菌などに対しても良好な効果を有し、その結果として、それらはまたアクネの処置(防除)、抗ふけ剤または真菌症(特に皮膚真菌症)の治療でも使用可能である。本発明に従う式1で表される化合物は幅広い範囲の作用を示し、特にグラム陰性細菌、例えば大腸菌および緑膿菌など、酵母菌、例えばカンジダ・アルビカンスなど、および菌・カビ、例えば黒色アスペルギルスなどに対しても同様に活性を示すことから、それらはまた例えば化粧品および/または薬調剤など用の優れた防腐剤にもなる。
【0019】
本発明に従う式1で表されるアルコールを最終化粧品(例えばクリーム、シャンプーなど)で用いる時の濃度を各場合とも化粧品の総質量を基準にして好適には0.0069から20%(質量/質量)の範囲、好都合には0.05から5%(質量/質量)の範囲にする。
【0020】
(a)ふけの原因となる微生物、(b)体臭の原因となる微生物、(c)アクネの原因となる微生物および/または(d)真菌症の原因となる微生物を化粧的および/または治療的に処置する好適な方法では、本発明に従う式1で表される1種以上の化合物を抗菌活性量で人または動物の体に局所的に塗布することで、存在し得る微生物または有機体の増殖を抑制しそして/またはそのような有機体を死滅させる。
【0021】
しかしながら、本発明に従う式1で表される化合物は、勿論、人または動物の体に塗布することを意図するばかりでなく、また、例えば(e)無生物材料の上または中に存在する微生物を処置する目的に加えて(f)腐敗し易い製品を保存する目的で用いるにも適する。
【0022】
本発明に従う式1で表される物質は、また、芳香組成物(香料組成物)の一成分としても使用可能であり、例えば、最終芳香製品に抗菌作用を与え得る。特に好適な芳香組成物は、(a)香料を知覚効果を与える量で含有し、(b)前記式1(ここで、Rはこの上に示した意味のいずれかを持ち得る)で表される1種以上の化合物を防腐作用を与える量で含有しかつ(c)場合により1種以上の賦形剤および/または添加剤を含有して成る。最終化粧品の中の香料の比率はしばしば約1%(質量/質量)の領域であることから、本発明に従う式1で表される化合物を含有させた香水は、好適には、前記式1で表される1種以上の化合物を約5−50%(質量/質量)含有することになるであろう。前記式1で表される物質が有する固有の臭いは僅かのみであるか或は完全に無臭でさえあるのが特に有利であることを確認した、と言うのは、そのような特徴によってそれらが芳香組成物に入れる防腐剤として用いるに適するか否かが決まるからである。
【0023】
本発明は、また、抗菌性組成物にも関し、この抗菌性化合物は、(a)本発明に従う式1(ここで、Rはこの上に示した意味のいずれかを持ち得る)で表される1種以上の化合物を抗菌活性量で含有することに加えてまた(b)成分(a)と適合し得る担体物質も含有する。
【0024】

【0038】
好気増殖する細菌微生物の試験微生物懸濁液の調製をMueller−Hintonブロス(broth)(Merck、Ref.1.10293)のインキュベーションで実施したが、このインキュベーションを、関連試験微生物の個々の数個のコロニーを接種して36℃で実施した。顕著な濁りを得た後、この懸濁液に無菌栄養ブロスをそれの濁りがMcFarland Standardの0.5(約1.5x108CFU/ml)に相当するような量で加えた。
【0039】
他の試験微生物懸濁液の調製では、試験菌株を上述した固体状栄養培地の上で培養し、無菌綿棒を用いて収穫した後、Mueller−Hintonブロスを懸濁液の濁りがMcFarland標準の0.5に相当するような量で用いて取り上げるか或は希釈した。

Many different bacteria live on human skin. Most of these bacteria are not pathogenic and are not related to the physiological state of the skin and the odor of the skin. On the other hand, other bacteria can have a decisive impact on skin health. Some of the microorganisms that have a substantial effect on the flora of human skin are listed in Table 1.
[0006]
[Table 1]
[0007]
Substances produced in the body and substances contained in sweat, such as unsaturated fatty acids, are broken down by bacteria, resulting in severely affecting the good state of the body from precursors with a somewhat weak odor. A decomposition product is produced with an unpleasant odor that can be imparted. In cosmetics, for the purpose of preventing the generation of substances that contribute to body odor, products that suppress the generation of sweat (so-called antiperspirants) or bacteria on human skin (which contribute to the generation of odor) Substances that suppress growth (deodorants) are used. Bacterial species such as Staphylococcus epidermidis, Corynebacterium xerosis and Brevibacterium epidermidis are generally a decisive factor in the development of armpit and foot odor or body odor. Accordingly, there is a continuing need in the cosmetic industry for new agents to treat microorganisms that cause these and other body odors, including armpit and foot odors.
[0008]
The microorganism that causes acne is Acne Propionbacterium, which is an anaerobically growing microorganism. The cosmetic industry is constantly searching for agents to treat such microorganisms and other microorganisms that cause acne.
[0009]
All areas of human skin can be infected by fungi [especially dermatomycoses and onychomycosis]. Skin areas that can accumulate moisture and warmth as a result of wearing clothes, shoes or jewelry are particularly frequently affected. Diseases caused by bacteria and molds in the fingernails and toenails are particularly uncomfortable. Different species of the genus Trichoderma and Epiderma are often a decisive factor in the development of mycoses. The cosmetic industry is constantly researching new agents for treating microorganisms that cause these and other mycoses.
[0010]
In addition, in the field of hair care, there is a strong study of substances to treat the microorganism, Malassezia fluflu (which is a decisive cause of dandruff) and other microorganisms that cause dandruff. ing.
[0011]
Within the context of this context, “treatment” is understood to mean some form of influence on the microorganisms by means of inhibiting the growth of the microorganisms concerned and / or killing the microorganisms concerned.
[0012]
In addition, the cosmetic and pharmaceutical industries are constantly seeking agents suitable for use in preserving perishable cosmetic or pharmaceutical products.
[0013]

-Toxicologically accepted,
-The skin is well received,
-Is stable (especially in normal cosmetics and / or pharmaceutical preparations),
-Preferably odorless, and
-Cheap to manufacture (ie using standard methods and / or starting from standard precursors)
You have to take into account what you need.
[0014]
The study of a suitable (active) substance having a sufficient degree of one or more of the above characteristics is more difficult for a technician in the field, on the one hand the chemical structure of one substance and on the other This is because there is no clear dependency between the biological activity and stability that s. Moreover, there is no predictable relationship between antibacterial action, toxicological acceptability, skin acceptance and / or stability.
[0015]

2. Experiments to measure the antibacterial activity of 4-methyl-4-aryl-2-pentanols
4-methyl-4-aryl-2-pentanol represented by the above formula 1 (wherein R may have any of the meanings indicated above) is used for controlling microorganisms that contribute to body odor. What has been found to be very particularly suitable for this date goes back to a series of experiments that investigated the particularly related microorganisms Staphylococcus epidermidis, Corynebacterium xerosis and Brevibacterium epidermidis. However, not only are the results of saying that Staphylococcus epidermidis, Corynebacterium xerosis and Brevibacterium epidermidis are inhibited, but the results of further testing are also shown below. In particular, the activity of said 4-methyl-4-aryl-2-pentanol has also surprisingly been tested for further microorganisms such as Malassezia furfur, Trichoderma trichoderma, Acne propion bacteria, It was also high for Candida albicans and black Aspergillus, and as a result, they found that they have additional fields of use.
2.1 General test conditions
In the demonstration of the antibacterial action of the substance synthesized according to Example 1-4 (formula 2-5), it was demonstrated using the agar dilution method based on DIN 58 940 / ICS and DIN 58 944 / ICS. A freshly prepared Mueller-Hinton agar [Merck, Ref. 1.05437 or Wilkins-Chalgren agar boiler, Oxoid, Ref. 6.7 ml of CM 643, 10 g of agar supplemented per liter] was added, and while maintaining the liquid state at 50 ° C., 3.3% (volume / volume) = 0.3 ml of the sample diluted to various concentrations added. For the test microorganism, Malassezia fullflu, Mueller-Hinton agar containing 3% Tween 80 (Merck, Ref. 8.22 187) was used.
[0034]
2.6 ml of a 3.3% sample was used and diluted with ethanol (96%; Merck, Ref. 1.00971). Progressive 2: 1 dilution with ethanol (96%) produced individual additional test concentrations in a series of dilutions, which were prepared in the form of a geometric series.
[0035]
Further dilution with test agar (0.3 ml sample or equivalent dilution + 8.7 ml agar) achieved in each case a concentration 30 times lower than the final concentration (in each case corresponding to an initial concentration of 1100 ppm) . The concentrations shown below relate to high purity materials and were converted to ppm. Agar plates were poured in duplicate for each test concentration and nutrient medium.
[0036]
In each case, the following experiment was performed using two agar plates:
K1: 9.0 ml Mueller-Hinton agar (no inoculation)
K2: 8.7 ml Mueller-Hinton agar (no inoculation)
+0.3 ml ethanol (96%)
K3: 8.7 ml Mueller-Hinton agar (with inoculation)
+0.3 ml ethanol (96%)
K4: 9.0 ml Mueller-Hinton agar (with inoculation)
K5: 9.0 ml Mueller-Hinton agar (no inoculation)
+ 3% Tween80
K6: 9.0 ml Mueller-Hinton agar (no inoculation)
+ 3% Tween 80 + 0.3 ml ethanol (96%)
K7: 9.0 ml Mueller-Hinton agar (with inoculation)
+ 3% Tween 80 + 0.3 ml ethanol (96%)
K8: 9.0 ml Mueller-Hinton agar (with inoculation)
+ 3% Tween80
K9: 9.0 ml Wilkins-Chalgren agar (no inoculation)
K10: 9.0 ml Wilkins-Chalgren agar (no inoculation)
+0.3 ml ethanol (96%)
K11: 9.0 ml Wilkins-Chalgren agar (with inoculation)
+0.3 ml ethanol (96%)
K12: 9.0 ml Wilkins-Chalgren agar (with inoculation)
The test plates were solidified and dried (at 37 ° C. for about 1 hour) and then inoculated in 1 μl each with a suspension of the test microorganisms listed below in the form of dots. Growing aerobically growing bacteria (Brevibacterium epidermidis, Corynebacterium xerosis, Staphylococcus aureus, Staphylococcus epidermidis) on Columbia blood agar (BioMerieux, Ref. 43049) for the purpose of checking purity and discrimination I let you. The mold black Aspergillus, the yeast Candida albicans and the skin fungus Trichophyton fungus cultivar were cultured on Sabouraud agar (BioMerieux, Ref. 43555). Of Sabourad-HLT agar containing the inhibitor of Malassezia furflu (the following are added: Tween 80: 1%, lecithin: 0.3%, histidine: 0.1%, Merck, Ref. 1.18368) Incubated above. Acne Propionbacterium was cultured on Schaedler agar (BioMerieux, Ref. 43273). Further data on the microorganisms tested can be seen in Table 1.
[0037]
[Table 2]
[0038]
The preparation of a test microbial suspension of aerobically growing bacterial microorganisms was carried out in an incubation of Mueller-Hinton broth (Merck, Ref. 1.10293), which was carried out for several individual test microorganisms. Were inoculated and performed at 36 ° C. After obtaining a noticeable turbidity, the suspension is sterilized with sterile nutrient broth that has a turbidity of 0.5 (approximately 1.5 × 10 × 10 McFland Standard).8In an amount corresponding to CFU / ml).
[0039]
For the preparation of other test microbial suspensions, the test strain is cultured on the solid nutrient medium described above and harvested using a sterile cotton swab, and then the Mueller-Hinton broth is suspended in a McFarland standard. Used in an amount corresponding to .5 or taken up or diluted.
[0040]
All test microbial suspensions except for Acne propion bacteria were again diluted 1:10 with sterile broth and their microbial counts were determined by a surface method using a Spiralometer (Results: see Table 1).
[0041]
The inoculated plate was incubated under the conditions shown in Table 2 and then evaluated. The MIC (minimum inhibitory concentration) is considered to be the lowest concentration of active compound when macroscopically no growth occurs. Individual colonies were evaluated to have minimal growth, little growth, or inhibition when very small.

Even if all the substances listed in Table 3 are less than 0.15%, Gram-positive bacteria that cause body odor, such as Staphylococcus epidermidis, Corynebacterium xerosis, Brevibacterium epidermidis, etc. It was possible to observe that the growth of the cells was clearly suppressed. In this connection, (R / S) -4-methyl-4-p-cumenyl-2-pentanol showed the most potent activity [Staphylococcus epidermidis: 138 ppm = 138 μg / ml; Corynebacterium xerosis : 69 ppm = 69 μg / ml; Brevibacterium epidermidis: 138 ppm = 138 μg / ml]. Similarly, the activity against Acne Propionbacterium, which is a cause of acne, was particularly remarkable in the case of (R / S) -4-methyl-4-p-cumenyl-2-pentanol (138 ppm = 138 μg / ml). However, activity could also be observed for substances 2, 3 and 5. On the other hand, for yeasts such as Candida albicans and molds, (R / S) -4-methyl-4-phenyl-2-pentanol (formula 2) and (R / S) -4-methyl- 4-p-Tolyl-2-pentanol is the most effective substance. Since the range of action exhibited by the substances or also mixtures of the substances is very wide, they can also be used as preservatives.
